CubeCart Modification / Customisation

We have a client with an exisiting CubeCart site (4.3.3) which has many modifications already. We are looking for a price for the following 2 modifications MODIFICATION 1 Overview The client requires the ability to add personalisation to thier products with a preview of how the personalisation will look on the item. Steps The customer selects a product, quantity and colour and ticks "Add Personalisation". On the next page they get the option to add the text for their personalisation, this text then appears overlayed on a image of the product Example Please see [login to view URL] MODIFICATION 2 Overview The client currently has a UK site but want a site for France (EURO). So they need to add EURO pricing for each product - not a conversion an actual price for the each product in UK GBP and EURO. Steps The customer needs to register before seeing the prices - this already happens on the UK site. We would also need the ability for customers visiting the site from France to be registered as a "French" client
